This is not a traditional ESL textbook; rather, it is a self-help book for shy people. However, as a teacherof ESL in the states, I have found that several of my students have difficulty making friends outside the classroom. The book "How to Start a Conversation and Make Friends" by Dan Gabor (1983, Simon and Schuster) (ISBN 0-671-47421-9) has some good tips for people who have trouble getting started with a conversation, including body language tips and a list of "50 Ways to Improve Your Conversations." For the most part, the English in it is pretty easy (apart from a few idioms that would need explaining). After I had my class listen to a segment of the book on tape, several people came up to me and asked about thename and title of the book. I think I originally bought it at Barnes and Noble.
